Patent GB-2212996-A (GB)
Title: Electrical load control system
Inventor: LUCHACO DAVID G
IPC: H05B37/02
Filed: 1989-02-21
Abstract: A load 14, eg. a lamp or inductive or capacitive load, is switched by means of a triac 18 which is ON or OFF when a bistable latch 24, 26, 28 in a control circuit 20 is in an ON or OFF state. The state of triac 18 is charged by momentary closure of a local or remote switch Pb or Pb'. When the latch is ON, triac 18 is triggered just after each zero crossing and a capacitor C1 charges via D8 and Q1 in that part of each positive half cycle before triac 18 turns ON. If the switch Pb or Pb' is closed transistor Q3 turns on to discharge C1 through reset coil 28 so that switch 24 turns off triac 18. A capacitor C2 then charges via D10 and Q2 which is turned off when the capacitor C2 voltage causes Zener diode D2 to conduct. Subsequent closure of switch Pb or Pb' causes capacitor C2 to discharge through set coil 26 so that switch 24 and triac 18 are turned ON. Transistors Q1 and Q2 are held off whenever a switch Pb or Pb' is closed to prevent charging of capacitors C1, C2 thereby preventing repeated switching of the latch circuit when Pb or Pb' are held closed. If two switches Pb, Pb' are successively closed in such a short time that capacitor C1 or C2 is not charged sufficiently to fully energise coil 26 or 28, switch 24 may become stuck between ON and OFF. In that event, a transistor Q4 provides a charging path for capacitor C2 so that switch 24 and triac 18 can subsequently be turned on. <IMAGE>

Patent GB-2221802-A (GB)
Title: Electric motor including clutch actuated by magnetic attraction of rotor core
Inventor: TSUTSUMI SHUNSAKU
IPC: E05B81/46
Filed: 1989-06-23
Abstract: An electric motor (21) is disclosed having clutch means (22) which is formed of a magnetic material. When winding means (44) wound on a core (45) of the motor is energised, the core is electrically magnetised and attracts the clutch means for electromagnetic coupling so that the core and the clutch means may be rotated in the combined condition to operate a driven member drivingly connected with the clutch means. Upon de-energisation of the winding means, the clutch means may be rotated separately from the core to permit movement of the driven member by easy manual operation independent of the core. Either the clutch or the core and shaft assembly may move relative to the housing and a spring 52 may be provided to assist disengagement. <IMAGE>

Patent GB-2235796-A (GB)
Title: Ioniser
Inventor: MACFARLANE WILLIAM IAN
IPC: H01T23/00
Filed: 1990-07-27
Abstract: An ioniser (10) which is used to increase the level of ions in a room includes voltage control circuitry which produces and maintains a high negative voltage of the order of 5 KV across a capacitor (C13) connected to the ion emitter (12). This is achieved by feeding back the voltage across the capacitor (C13) so as to bias a transistor (VT1) on the primary side of transformer (TX1) such that when the voltage is low, capacitor (C10) is allowed to discharge pulses through the transformer (TX1) and hence increase the voltage across capacitor (C13). As the voltage approaches the desired value, transistor (VT1) gradually switches off so that capacitor (C10) cannot discharge through the transformer. The high negative voltage is transmitted to the ion emitting points (13) which emit negative ions into the atmosphere of the room. <IMAGE>

Further dampers for torsional and/or bending vibrations may be mounted on the carrier. <IMAGE>
Patent GB-903054-A (GB)
Abstract: 903,054. Valves. ROBERTSHAW-FULTON CONTROLS CO. Feb. 24, 1959 [June 13, 1958], No. 6370/59. Class 135. A fuel burner control comprises first valve means 20 controlling flow to a main burner outlet 14 and a pilot outlet, thermo-electric safety valve means 42 permitting or shutting off flow to both outlets, the operating means for valve 20 being reciprocable for resetting valve 42 through member 54. On turning knob 60, having a splined connection at 64 with cock 20, to the pilot position, a tang on a splineconnected ring 90 snaps out of an undercut recess in cover 78 so that springs 70, 89 move the knob outwards and give an audible and visual indication that the cock is in the pilot position so that knob projections 84 may enter cover slots 88 when the knob and stem 54 are depressed to lift valve 42 from its seat 24 on the cock. On igniting the pilot burner, a thermocouple energizes an electromagnet which holds valve 42 open and allows knob 60 to be released and rotated to open the cock to the main burner outlet. To close the cock, the knob is rotated in the opposite direction to a pilot position stop and then depressed and rotated to engage the tang in the undercut recess.

Title: Dry gas meter
Inventor: PYE ALFRED EDWARD
IPC: G01F3/22
Filed: 1991-03-12
Abstract: A dry gas meter comprises two gas chambers (11, 12), across each of which a flexible diaphragm (13, 14) works. Each chamber is asymmetric, being trapezoid in cross-section, and has a flag rod axis (26, 27) located at its narrower end. An angle A of 10 DEG  lies between the converging sides (40, 41) of the chamber. Each diaphragm is subjected to less stress because it follows more closely the arcuate movements about the flag rod axis so that resistance to the movement and consequent energy loss are reduced. <IMAGE>

Title: Exercising device
Inventor: FOSH MARK WILLIAM
IPC: A63B21/16
Filed: 1991-09-05
Abstract: A movable driving means (1, 2, 9) is moved by a user in the course of exercising. The driving means is connected to a force applying means (7, 8, 15) via a gearing-up means (3, 5, 13). A spring (7) provides a resistance to at least part of the motion of the gearing up means (3, 5, 13), so that for a single stroke of the driving means (1, 2, 9), the spring (7) is compressed and extended many times. Because of the gearing effect the spring (7) need only be relatively weak, and the pulsed resistance is of high enough frequency to seem relatively smooth. <IMAGE>
